Description

A remote overflow exists in Mozilla Foundation's Network Security Services (NSS) libraries. The vulnerability is due to inadequate error checking in the Network Security Services (NSS) code that is responsible for handling the Client Master Key. A remote attacker can exploit the vulnerability with a specially-crafted SSLv2 certificate containing a Client Master Key with invalid length values. This may result in a stack-based buffer overflow allowing the attacker to crash the affected server or to execute arbitrary code in the context of the affected server, resulting in a loss of availability and/or integrity.

Classification

Location: Remote / Network Access
Attack Type: Input Manipulation
Impact: Loss of Integrity, Loss of Availability
Exploit: Exploit Public, Exploit Private
Disclosure: OSVDB Verified, Vendor Verified

Technical
